Power-On Hours Count
Reports the cumulative number of power-on
hours over the life of the device. However,
the On/Off status of the Device Initiated
Power Management (DIPM) feature will
affect the number of hours reported. If DIPM
is turned On, the recorded value for
power-on hours does not include the time
that the device is in a "slumber" state. If
DIPM is turned Off, the recorded value for
power-on hours should match the clock
time, as all three device states are counted:
active, idle and slumber.
